WORD-COUNTING ATTACHMENT FOR TYPE-WRITING MACHINES.

SPECIFICATION forming part of Letters Patent No. 701,840, dated June 10, 1902.

Application filed October 8, 190

To all whom it may concern.-

Be it known that I, HENRY BoUNDs CARY, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in W'ord-Countin g Attachments for Type \Vriting Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a novel attachment for type-writing machines of the type known as bar-machines, which shall during the operation of the machine automatically count and display the number of words printed by the machine.

In the use of type-writing machines the product of their operation is usually paid for by the folio or number of words, and it involves considerable time and labor to determine With any degree of exactness the number of words produced by the typewriter. This task is especially laborious where the amount of work is large-such, for instance, as the report of court proceedings, speeches, dac.

My invention has for its object to provide an attachment for type writing machines which shall be simple and economic of construction and readily applied to the machine and which shall with mechanical accuracy register every word and figure printed by the machine, so that when the work has been completed there will be an absolutely correct rec 0rd thereof.

With these ends in view my invention consists in the construction, arrangement, and adaptation of the counting or enumerating attachment hereinafter particularly described and claimed.

In order that those skilled in the art to which my invention appertains may fully understand the same,-I will proceed to describe its construction, the manner in which it is applied, and the way in which it operates, referring by numerals to the accompanying drawings, in Which Figure 1 is a side elevation of an ordinary Remington type-writing machine with my improved counter applied thereto. Fig. 2 is a bottom plan View of the same. Fig. 3 is a l. SerialNn.78,0Z3. (No model.)

1 side elevation with the parts of the typewriting machine broken away and showing in clotted lines the carriage-frame moved to the upper case. Fig. 4 is an enlarged detail section on the line as o: of Fig. 6 and showing one of the type-bars and the swing-bail in two positions. Fig. 5 is a detail perspective view of the rocking frame. Fig. 6 is a perspective view of my improved attachment segregated from the type-writing machine. Fig. 7 is a detail perspective view of the arm connecting the rocking frame with the wordregistering indicator; and Fig. 8 is an inside elevation, on reduced scale, of the right end of the attachment and showing the vibrating levers which transmit the motions of the attachment to the registering indicators.

Similar numerals indicate like parts in the several figures of the drawings.

1 is the frame of an ordinary Remington type-writing machine, 2 the paper-carriage mechanism, (shown in dotted lines,) and 3 the ordinary key-levers.

My improved attachment is designed to be located on the under side of the type-writing machine and in position to be operated upon by the key-levers 3. It is secured in proper position upon the frame of the machine through the medium of two end pieces 4 5, having kerfs to receive the frame of the type-writer and to which they are rigidly secured by binding-screws threaded in suitable holes 7 or in any other desired manner. The end pieces 4: 5 are connected by a stiff casting or flat bar 8 and are further braced by a rod 9, (see Fig. 4,) which constitutes the fulcrum upon which the vibrating or rocking frames hereinafter described are mounted. The fiat bar 8 may be cast integral with the end pieces at 5, or it may be made separate and secured thereto by screws in any suitable manner.

The auxiliary strengthening-rod 9 is preferably formed with a head 10 and its opposite end threaded into the end piece 5, as shown, or both ends may be formed with threads to receive nuts on the outside of the end pieces at 5 and shoulders to bear against the inside faces of the end pieces. This strengtheningrod 9 passes through the ends of a swinging bail l1 and rocking frame 12 and constitutes a fulcrum upon which. said bail and frame move. The bail 11 and the frame 12 are held in proper relation to each other and to the other parts of the attachment preferably by tubular sleeves l3, surrounding the bar 8.

The rocking frame 12 is rectangular in form, as best shown at Fig. 5, and may be made in one piece, or the four parts may be made separately and connected together by screws or otherwise, as may prove most desirable for manufacture. The ends of this frame are provided with holes 14-, through which the fulcrum-rod 9 passes, and the ends of the bail 11 are likewise provided with holes for the passage of said rod, so that in assembling the parts of the machine and while the rod 9 is being put in position the sleeves 13 are located as shown and hold the bail 11 and frame 12 against lateral displacement, while in no way interfering with their necessary swinging or vibratory action. The front bar of the frame 12 is formed with a flat-faced contactfinger 15, against which the end of the spacing-bar frame strikes whenever it is used to space a word and which action causes the frame 12 to be rocked upon the fulcrum-shaft 9, thus bringing the front of said frame down to the plane of the lowest movement of the space-bar frame, at which localityit remains until it is returned to normal position by the striking of any key representing the first letter of a word or the striking of a key representing any character which should be counted as a word, as will be presently explained. This front bar of frame 12 is also formed with vertical contact-fingers 10, 17, and 18, which lie in the path of the vertical movement of the keys used for printing the punctuation characters and which. effect the lowering of the frame 12, as already described. The rear bar of the frame is formed with a series of contact-fingers 19, which are so located as to intersect the path of the vertical movement of the several key-levers carrying letter characters whether used in lower or upper case, and the gates or spaces 20 are located within the path of the key-levers which carry the numerals and signs,which are usually counted as wordsin computing the work done 011 a typewriting machine. The end bars of the frame 12 are formed each with a gate 21, so that as the frame 12 is vibrated it may freely pass a rocking shaft 22, (see Fig. 6,) the purpose of which will be presently explained.

The rocking frame 12 is so balanced on the fulcru1n-bar9and the frictional contacts are such that it will remain in its alternate positions until alternately acted upon by the keylevers.

The swinging bail 11 is vibratively mounted upon the fulcrum-bar 9, as clearly shown at Fig. (3, and carries atits free ends the shaft 22, Whichis rotatively mounted therein. This shaft is formed with a radial or crank arm 23 atone end, (see Fig. 6,) which is rotatively conneeted with an arm 2 1, the forward end of which is pivoted to a vertical arm 25, vibra has its right-hand end rotatively mounted in the rear end ofa flatlever 31, which is pivoted at 32 to the inside of the end piece -11, (see Fig.

8,) so that said shaft is free to be rotated upon its bearing in said lever and its bearing at the other end in the arm 2-1.

Arranged in fixed relation upon the shaft 22 are a series of contact-cams 33, which are arranged. opposite the gates 20 in the rear part of the rocking frame 12 and in the path of those key-levers which are depressed to cause the printing of numerals, and as said levers contact with such cams the swinging bail 11 is depressed and the rocking shaft travels within the gates 21 in the ends ofthe rocking frame 12. The faces of the several cams 33 are of such predetermined design that when the paper-carriage is shifted and the shaft 22 is rocked through the medium of its connections already described with the shifting-bar of said carriage such cams as are in alinement with such keys as are used in printing the signs or abbreviations in the upper case as are usually counted as words will be contacted with and the bail 11 tilted in the same manner as already described, while all other cams will be below the sweep of the other key-levers, and consequently according to the construction and arrangement of the several cams all numerals and signs maybe counted as presently described which are customarily counted as words, and all signs not usually counted as words are not counted by the attachment. The swinging bail is restored to its normal position after its rear end has been depressed through the medium of a flat spring 31, secured centrally to the barS between the end pieces 4: and 5, the ends of which spring bear against the under side of: the rearends of the swinging bail, as clearly shown at Fig. 6.

I will now describe how the movement of the rocking frame 12 and the swinging bail 11 cause a record to be made of the number of words, figures, and signs.

Secured to the end piece 1 in proper position is any suitable numbering or registering device 35, which is designed to record the number of ordinary words printed by the type-writing machine, and adjacent to it is another numbering or registering device 23b for recording the numerals or signs printed by the machine and which are usually counted as words.

37 is a knee plate or lever pivoted to the inside of the end piece 1:, as clearly shown at Fig. 8. Thelower end of this leverisloeated within a slot 38 (see Fig. 5) in the end of the front of the rocking frame 12, and the upper end is connected with the registering device 35 in such manner that the vibration of the lever 37 will cause the register 35 to act. In the drawings I have shown this connection by slotting the upper end of the lever 37 and connecting it with a crank 38 on the shaft of the registering device, so that when all the parts are in normal position the rear of the rocking frame 12 is in its most elevated position and such that when any one of the letters of the alphabet-keys is struck the keylever will contact with the particular contactfinger 19 below such lever, whereupon the frame 12 will be rocked, so as to elevate its front portion, which movement will cause the knee-lever 37 to vibrate upon its pivot, thus throwing its upper slotted end toward the operator, and consequently throwing the crank 38 in the same direction and in position to cause the numbering or registering device to make a register of one number when the crank 38 is thrown back. Now when this condition has been established, as it will be whenever a single key has been struck, the rear portion of the frame will not be struck by the depression of any other keylever until after the completion of the word, and when the spacing-bar is struck and contact is made with the contact-finger 24 or a punctuation-key is struck and contact made with one of the contact-fingers 16, 17, or 18, in which event the front portion of the swinging frame is depressed, rocking the same upon its fulcrum-shaft 9 and causing the rear portion of said frame to be elevated into the position where the contact fingers 19 may again be struck, this movement of the swinging frame 12 causes the knee-lever 37 to be vibrated and the crank 38 to be thrown back, which in turn causes the registration to be made by the device 35. If a key carrying a numeral or sign be struck, then such key-lever contacts with the respective cam 33 on the shaft 22 and causes the same to be depressed against the action of the flat spring 34 and carrying with said shaft the swinging bail 11, and as the shaft 22 is free to travel vertically in the gates 21 in the ends of the swinging frame 12 without affecting the same; but this downward movement of the rear of the swinging bail causes the flat lever 31 to be vibrated upon its pivot 32, thus raising its front end, which is connected in any suitable manner with the secondary registering device 36; but I have shown it connected by a crank 39, passing through a slot in the upper end of the lever in substantially the same manner as already described as to the connection between the registering device 35 and the knee-lever 37.

From the foregoing description it will be seen that when my improved attachment is properly secured to the machine none of its parts arein any manner obstructive to the ordinary use of the type writing machine and that it may be made independently of such and readily applied and removed when desired. It will also be seen that it is economical of construction, the parts readily assembled and interchangeable and absolutely positive and accurate in operation, and is accommodated to every possible and usual use of the typewriting machine and that the attachment is absolutely passive at all times except when it is necessary to register a word or equivalent sign or abbreviation. It is equally efficient in upper or lower case printing and does notinterfere with the use of the spacingbar before the printing of a word, figure, or sign nor subsequent to the register of the same and before printing is again begun. It registers nothing that should not be registered, and it will be obvious that when a punctuation-key is used the same effect is produced as occurs from the use of spacingbar, so that in either event the register is made only upon the completion of the printing of a word, numeral, or sign.

I wish it to be distinctly understood that I do not limit myself to the use of any particular kind of registering device or devices, as my attachment may by the exercise of ordinary mechanical skill be so connected with any kind of registering device as to properly operate the same, and while I have shown my attachment as constructed with especial reference to its use with what is known as a Remington type-writing machine it will be understood that it may be made applicable to other machines by simply varying the details of construction and arrangement of the several parts of the attachment without departing from the genus of my invention, which consists in the broad idea of mechanism intermediate of a counter or register and the vibrating levers of the keyboard of a machine which shall cause the register to count the completion of a word printed or the printin g of numerals or characters usually counted as words and without affecting such registering mechanism at any other time during the use of the type-writing machine.
